thIECl'I-IGATEON forming part of Letters Patent No. 328,977, datedOctober 2'7, 1885.

Application can May 13, 1884. Serial No. 131,366. (No model.)

To aZZ whom it may concern/.-

Be it known that 1, DAVID ROUSSEAU, of Mott Haven, inv New York city,State of New York, have invented certain new and useful Improvements inElectric Gas-Lighting Burners, of which the following is aspecification.

My invention applies to that class of burners in which the movement of alever pivoted on the burners operates the gasvalve to turn on the gasand simultaneously actuates the electrodes to produce theigniting-spark.

In most all burners of this type the valve used is a rotaryfriction-plug of the common form, and is revolved by a ratchet movementof the lever. In aformer application filed by me October 6, 1883, No.109,071, I show a burner provided with a minute double-seatingpuppet-valve, which works without packing or friction in a directionacross the gas-passage ofthe burn er, and it is operated by a valveleverwhich is actuated by cam-pins ona ratchet-wheel, which latter isrevolved by the pawllever or sparking-lever, and so arranged that eachalternate forward step of the lever and ratchet will open the valve andignite the gas, while each intermediate forward step will close thevalve and extinguish the gas, the backward movement of the pawl-leverbeing always idle.

Now, in my present device I dispense entirely with the ratchet and camwheel between the valve-lever or sparking-lever, and I form a directengagement between the valve-lever and the sparking-lever, so that theforward movement of the lever opens the valve and produces theigniting-spark, whereas the back movement of the lever positively closesthe valve. I also pivot a large pawl or pawl-1ever on the sparking-leverand limit its move ment on the sparkinglever by a stop, and connect thependent manipulating pull to one arm of this pawl-lever, while the otherarm of the pawl-lever is arranged to engage a looking projection on theburner in the arc of motion of the lever, and to this end of the pawl isattached a second pull-cord. When, therefore, the first cord is pulled,the pawl and sparking-levers move around together, and thus open thevalve and separate the sparking-points until, finally, the tip of thepawl rides over the projection, and thus locks the parts in the openposition. "When, however, the second cord is pulled, the pawl isreleased, and both pawl and electrode lever are caused to fly back bythe action of a spring, so as to close the valve and extinguish the gas.One of the said cords passes through a perforated knob or loop slidingon the other cord, so that both cords can be held in the same hand andeither operated. easily to close or open the valve without causingeither cord to fly out of place when the lever is allowed to spring backto close the valve.

My present invention therefore consists, mainly, in the features aboveoutlined, as hereinafter fully set forth.

In the drawings annexed, Figure 1 represents a front elevation of myimproved burner with the valve closed and the parts in their positionsof repose. Fig. 2 is a similar view with the pawl and sparking-leverpulled over into their locked position with the valve opened. Fig. 3 isa side elevation of the burner with the parts in the position of Fig. 1,and viewed from the right or valve side of the burner. Fig. 4 is a rearelevation of the burner with the parts in the position of Fig. l, andshown partly in section to illustrate the action of the valve, 850.

Referring to the figures, a indicates the body of the burner, which ispreferably cast in brass, as usual, having a gas passage extendingthrough it, with a screw-socket at the base to screw onto the fixture,and a ground socket at the top to receive the lava or other jet tip, asusual. The gas passage I) does not extend straight through the burner,but is somewhat eccentric and zigzag, as shown well in Fig. 4,substantially the same as in my former burner, and at the bend or zigzagpart of the passage is formed a small recess or valve-chamber, c, inwhich a small double-faced puppet-valve, (1, works, as shown best inFig. 4. The stem d of this valve projects freely through a smallscrew-plug, e, which is screwed into a threaded bore in the side of theburner coincident with the valvechamber 0. On the base of thevalve-chamber c is formed a conical-ground seat to meet with one face ofthe valve while the inner end of the plug 6 is formed with a similarseat to meet with the other face of the valve. The

extremity of the valve-stem (1 projects, of course, from the head of theplug 6, for operation .as shown, and it will now be readily seen thatwhen the valve is forced inward it will seat on the seat of thevalve-chamber, as shown in Fig. 4, and hence shut off the flow of gas tothe tip, whereas when the valve is moved outward it will seat on theseat of the plug 6, and prevent the escape or leakage of gas around theunpacked stem 61, while allowing the gas to flow freely to the jet-tip;hence this form and arrangement of valve, while being very simple, workswithout packing, and hence practically without friction, so that it istherefore operated with ease and certainty, and is hence admirablyadapted for burners of that class, as already set forth in my formerapplication.

Now, referring to Figs. 1 and 2, f indicates the main operating-lever ofthe burner, which may also be termed the sparking or electrode lever, asthe long arm f of the lever forms the movable electrode, which makes andbreaks contact with the yielding electrode 9, to produce the igniting-spark in the well-known manner of burners of this class, whichis sufficiently illustrated in ,the drawings, and needs no descriptionhere other than to state that the special arrangement of electrodes hereshown is the same as that patented to me in Patent No. 235,024, ofNovember 30, 1880. The electrode-lever f is an elbow-1ever pivoted atthe hub or bend on a stud or screw, h, which screws into a boss, 2', onthe side of the burner, as shown best in Figs. 1 and 3. In the loweredge of the hub of the lever is cut a wide notch,j, which is coincidentwith a tooth or projection, 70, which projects from the burner, and theends of this notch will strike against either side of the projection iswhen the lever is moved in either direction, and thus form stops tolimit said motions.

Around the boss 2', behind the lever f, is

coiled a spiral spring, Z, one end'of which en'- gages with theprojection 70, while the other end engages the arm f of the lever f, asshown best in Figs. 1, 2, and 3, so as to exert a constant tension toswing the lever in the position shown in Figs. 1, 3, and 4, with one endof the notch j against the tooth is. The lever f is also formed with ashort arm, f at about right angles to the arm f, and on the end of thisshort arm is pivoted a large pawl or pawl-lever, m, one arm of whichprojects outward in line with the arm f, while the other arm is curvedaround the hub of the main lever f, and is terminated with a pawltip, m,which normally lies against the projection k. play on the lever f and toand from the projection 7c sufficient to engage and disengage with theprojection by reason of a stop-pin, n, on the lever, which strikesagainst a shoulder, n, on the arm f.

The gas-valve d is operatively connected with the aforesaid levers bymeans of the prehended. a

The pawl-lever has only a limited forked valve-lever 0 p, which ispivoted on the pin 1) between ears 0, at the base of the burner, and oneor both of the arms 0 p of the valve-lever are springy or yielding. Thearm 0 of. the valve-lever is cleft at the tip and engages the groovedhead or tip of the valvestem, as well shown in Figs. 3 and 4, while theother arm, 19, is bent or curved to one side toward the hub of the mainlever f, and the tip of this arm is bent outward and engages with aneccentric slot, r, cut in thehub of the lever f, as well shown in Figs.1, 2, and 3. It will hence be observed that when the levers lie in theirposition of repose, as in Figs. 1, 2, and 4, the tip of the valve-leverwill be at the inner end of the eccentric slot and the valve will beclosed, (see. Figs. 1 and 4;) but if the leverf be swung around, as inFig. 2, the tip of the valve-leverp will traverse the slot r toward theouter end thereof, and the valve will be opened, as indicated in Fig. 2;whereas, if the lever f be again released it will fiy back into theposition of repose and positively close the valve, as seen in Figs. 1and 2. The throw of the slot 1" and the tension of the spring-arms 0 pof the valve-lever are such that a movement is imparted to the lever alittle greater than the throw of the valve, so that the overplus ofmotion slightly flexesthe spring-arms, and thus keeps a constant elasticpressure on the valve, to hold it snugly to its seat when moved eitherin or out, as will be readily com- Referring now to Figs. 1 and 2, itwill be seen that a pendent manipulating cord or chain, 8, depends fromthe tip of the pawllever m and connects to a perforated loop or knob, 3,while a second cord or chain, it, depends from the upper arm of thepawl-lever, passes through the loops, and connects to a manipulatingknob or ball, t.

The entire construction being now delineated, the operation will bereadily understood. WVhen, therefore, the burner is in a condition ofrepose with the gas turned off, the parts will be in the positions shownin Figs. 1, 3, and 4. If it is now desired to turn on and light thegas,it will only benecessary to seize the knob t and pull down the cord25. This will exert a downward strain on the pawl-lever m,

fore described and turn on the gas, and at the same time cause the arm fto first engage the electrode .9, as shown by dotted lines in Fig. 2,and then break contact therewith, as shown by full lines, and thusproduce an ignitingspark to light the issuing gas, while, finally, thecatching-shoulder of the pawl will ride over the projection k and fallinto engagement therewith, as shown by full lines in Fig. 2,

thus holding the parts locked in said position with the valve open andthe gas lighted,.as

will be readily understood. When it is desired to extinguish the gas, itis only necessary to seize the knob s and pull down the cord 8, whichwill slip the pawl m from the projection 70, and thus allow the leversto fly back into their positions of repose by the action of the springZ, as shown in Fig. 1, which will of course close the valve, as seen inFig. 4, and extinguish the gas.

It will now be seen that by having the main cord t pass through a loopon the releasingcord 8, the main cord is prevented from flying up highout of place when the levers spring back, as it is restrained by passingthrough the loop 8 and through the fingers which seize the loop, for itwill be seen that if the cord was left free it might be liable to bejerked up violently against the glass globes on the fixture and injurethe same; but this is prevented by the simple means described.

It will be also seen that the general mechanism of this burner is simpleand positive, and that one forward motion of the levers opens the valveand lights the gas, and one backward movement closes the valve and X-tinguishcs the gas, and by reason of the special form of valve used andthe direct operative connection between it and the sparkinglever thesemovements are rendered very easy and the action of the burner veryreliable.

It will be readily understood that in lieu of having the valve-leverengage with the sparking-lever by means ofthe cam-groove or eccentriogroove 7', any other operative connection may be used.

I do not of course confine myself to the cords t s for operating thepawl-lever, as these cords may be entirely dispensed with and thepawllever m operated directly by the hand.

What I claim is 1. The combination, with a gas-burner, of areciprocating puppet-valve moving in a chamber in the body of the burnerand controlling the gaspassage thereof, with a sparking-lever mounted onthe burner, a manipulating device for operating said lever, and a directpositive'operative connection between said lever and said reciprocatingvalve, arranged and operating substantially as herein set forth. 1

2. The combination, with a gas-burner, of

a reciprocating puppet-valve moving therein and controlling thegas-passage thereof, with the operating-lever f, pivoted on the burner,and provided with the cam-groove r, and with a second lever connectedwith the stem of said valve and engaged with the said groove in thelever f, and with means, substantially as set forth, for moving saidlever f back or forth and holding it in either of its positions,substantially as herein shown and described.

3. The combination, with a gas-burner, of a lever, f, pivoted on theburner, and. a valve controlling the flow of gas through the burner,with a positive operatiye connection between said valve and lever, withthe pawllever m pivoted on the lever f, having one arm projectingoutward and the opposite arm projecting inwardly and arranged to engagea stop or projection, k, with a manipulating-cord or its equivalentextending from the respective arms of the said pawl-lever, substantiallyas herein shown and described.
